Alexander Costello (Larax)

International Master Extraordinaire

Meet Alexander Costello, aka Larax—a chess warrior whose title of International Master was hard-earned and well-deserved, despite what their opponents might say after facing those relentless openings! Whether blitzing, bulleting, or calmly plotting rapid and daily games, Alexander’s prowess on the chessboard shines brighter than a queen on an open file.

A Journey Through the Ranks

Starting with humble blitz ratings barely scraping 1000 back in 2011, Alexander has since rocket-launched across the ranks, smashing a phenomenal blitz peak rating of 3010 in 2025—because why settle for “grandmaster” when you can flirt with mythic? Bullet and rapid rating beasts alike, they’ve kept opponents guessing with tactical surprises and a comeback rate north of 76%— because giving up is for pawns, not Larax.

Playing Style & Tactical Wit

With a penchant for deep endgames—68% frequency, to be exact—and an average of 67 moves per victorious game, Alexander plays the long game like a suspense novelist. Their psychological resilience is nothing short of legendary, boasting a tilt factor of just 16, reminding us all that even losing a piece isn’t catastrophic when your comeback win rate sits at almost 52%. Early resignations? Only about 11%, so don’t expect Alexander to quit before the fireworks start.

Favorite Openings & Secret Sauce

Alexander’s opening repertoire is a delightful mystery dubbed Top Secret—used in over 10,000 blitz games! But peek behind the curtain and you’ll find a love for rich, strategic battlegrounds like the Queen's Gambit Accepted Janowski Larsen Variation with a stunning 76% win rate, and the sly Caro-Kann Defense Advance Botvinnik Carls Defense rocking an 80% win rate. Against these, opponents might as well bring their coffee and settle in for the long haul.

Recent Adventures on the Board

Alexander’s recent victories are testament to their skill and stamina: outmaneuvering opponents with elegant resignations and tactical mastery in games where finesse meets ferocity. One shining example is a win by resignation in a Queen's Gambit Accepted Central Variation— proof that Larax’s opponents often wave the white flag well before the endgame.

Fun Fact

Did you know Alexander plays best around noon? So if you want to catch Larax at their absolute psychological peak, set your alarm for 12:00 and prepare for a battle.

In summary, Alexander Costello isn’t just climbing the chess ladder—they’re building a chess skyscraper. Meticulous, resilient, and cunningly tactical, Larax shows the chess world there’s no such thing as too many knights or too much time on the clock. Just don’t ask them to pick favorites: with their Top Secret moves, they keep us all guessing!

Hi Alexander!

You are sitting very close to a personal best (only a few points under 2794 (2025-03-23)) and have shown you can beat 2700-rated opposition at will. Below is a short roadmap for pushing through the next ceiling.

What already works

  • Active play & calculation. In the QGA win over carlocapau you uncorked 18…Qxf2+ and never looked back – a nice illustration of concrete thinking in sharp positions.
  • Conversion technique. When you reach an end-game edge (e.g. vs Mattechecetmatt) you keep the squeeze on, even with little time left.
  • Clock awareness. You usually stay up on the clock until the late middle-game – essential in 3-minute chess.

Growth areas

  1. Smoother development vs system openings.
    In the loss to GulamaliRises (London) two early pawn moves – …f6 and …b6 – weakened dark squares and delayed castling. Aim for a “minor-piece trio before flank pawns” rule of thumb. A simple antidote is:
    …d5 …Nf6 …Bf5 …e6 0-0 before you look at …c5/…c6/…f6.
  2. Tempo economy with the knights.
    In the Caro-Kann Advance (White vs ShazilTheGOAT2006) your knight wandered Na3-c2-e3-g2 while Black gained space. Before making a second knight move ask: Does this create a direct threat or improve a critical square? CriticalSquare
  3. Recognising central pawn breaks.
    A number of losses start with the opponent seizing the centre (…c5/…e5). Add one daily exercise where you pause and list all legal pawn breaks for both sides; it will train automatic awareness of those moments.
  4. Time allocation in won endings.
    Many of your wins end with <10 s on the clock. Reviewing the basic K+P, rook, and queen endings will let you blitz them out and save time for earlier critical positions.

Opening focus for the next week

As Black vs London: play 10 training games with the scheme …d5 …Nf6 …c5 …Nc6, castle, then break with …e5.
As White vs Caro-Kann: study the Short Variation model game “Karpov – Miles, Skellefteå 1985” and try h4-h5 before relocating your knight.

Mini-quiz (next study session)

  1. After 14…Nxd4 in the London game, what simple reply equalises for Black?
  2. Why is …f6 rarely sound before castling in Queen’s-pawn structures?
  3. Calculate the cleanest continuation for Black from this position (taken from your QGA win):

Keep up the great work, Alexander. One slow accurate move is worth three bullet-speed blunders – and you are only a handful of those away from the next milestone!
